For Selangor, the state and the federal government had been on opposing sides from the 12th General Election in 2008 until GE14, which contributed to the delay in the restructuring of the state's water infrastructure. One can relate to the challenges PAAB faced during the long-drawn-out saga between Selangor and the federal government involving the consolidation of four water concessionaires Puncak Niaga Holdings Bhd, Konsortium Abbas Sdn Bhd, Syarikat Bekalan Air Selangor Sdn Bhd (Syabas) and Syarikat Pengeluar Air Selangor Holdings Bhd (Splash).

Pengurusan Air Selangor Sdn Bhd was eventually formed and in 2015, it signed an agreement with PAAB, with the latter releasing up to RM2 billion to the former.

According to PAAB's annual report, Air Selangor migrated RM10.5 billion worth of assets to PAAB.
